Perio dental floss

This is dental floss I received when I bought toothpaste. I like dental floss because it can perfectly remove even food debris that brushing alone can't take away. Perio floss is very sturdy and doesn't break easily. It also has a slight sheen. I'd say it feels a bit like silk thread. Because it is very durable, it has a good grip, too. My teeth feel refreshed after brushing them with floss.
